THlLL-COUPLING JACK..

SPECIFICATION forming part of Letters Patent No. 279,005, dated June 5, 1883.

Application filed April 7, 1883. (No model.)

To all whom it may concern;

Be it known that I, JOHN PARENT, a citizen of the United States, residing at Brunswick, in the coimty of Cumberland and State of Maine, have invented certain new and useful Improvements in Devicesi'or Setting Thill- Rubbers, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to devices for insert ing thill-rubbers; and it consists in an arrangement of levers, one of which clasps the thill, while another, to which power is applied, rests against the axle, compressing the rubber and allowing the bolts to be taken out or put in.

In my drawings, Figure 1 shows a side view of my device attached to the thill and in position to compress the rubber. Fig. 2 shows a back view of the same. Fig. 3shows a plan or top view.

A is an elbow-lever, the upper end of which is formed into a clasp or hook which embraces the thill. The spur a projects underneath the thill in such a manner that when the upper end of lever A is hooked on the thill the point of the spur a will bear against the under side of the thill and form a stop. The two straight levers B B are piy'oted to the lower end of the lever A by means of the axle A. The levers B B are provided with holes b b.- The bifurcated lever O is hung to the levers B B by means of the pin D, which pass'esthrough the holes I) b. The pin D has a thumb=piece 011 one end, by which it may be 'formed into a handle.

handled. The upper end of the lever is \Vhen a rubber, E, is to be inserted it is placed in. position behind the thill, andbefore being compressed it is always wide enough to cover the holes through which the bolt H passes. The lever 'A is now hooked over the thill, as shown, and the. lever C adjusted on thelevers B B, so that a purchase may be obtained against the axle. If now the thill is held by the hand and force applied on the end of lever G, as shown by the arrow, the thill is pressed back against the rubber, which is compressed, thus allowing the bolt H to be put in. By the same process the bolt H may be withdrawn. The levers A and C, where they come against the carriage, may be covered with leather to prevent the varnish from being scarred. The two levers B B may be replaced by one lever hung to levers A and G in a manner substantially as here shown; but I consider the present form better.

Iiclaim as my invention- The device for inserting thill-rubbers, consisting of the lever A, one end of which hooks over the thill, combined with the levers B B, and the lever 0, having a handle onits upper end, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN PARENT.
